Definitions

  • the instant invention relates to an apparatus for contacting solids in the form of flowable lumps with liquids and, optionally, gases in order to dissolve said solids using a housing wherein a perforated vat holding the solids is disposed which, as the liquid flows around, forms a spouted bed.
  • DE 32 44 972 C1 (U.S. Pat. No. 4,590,289) discloses an apparatus comprising a reactor housing with a vat holding aluminium particles in the form of needles or chips arranged therein.
  • An aluminium alcoholate/alcohol mixture is set bubbling such that the fine aluminium particles are whirled up in the screen basket whereby the aluminium dissolves in the aluminium alcoholate/alcohol mixture.
  • the problem is solved by providing a rotary grate for holding the solids at least temporarily.
  • the volume turnover can be significantly increased by using said rotary grate. It is now possible to use large lumps, e.g. ingot off-cuts of more than 1 kg, which could not be used up to now.
  • a vertical pipe for placing the solids into the rotary grate, said pipe allowing to charge the solids from the top and to distribute them evenly in the screen reactor space.
  • said vertical pipe is provided with a joint such that the lower pipe outlet can be shifted between edge and center of the rotary grate.
  • the pipe is adjustable by means of a device which is steerable from outside.
  • the basket-like rotary grate is disposed on a central, vertical shaft protruding from the top of the reactor.
  • the protrusion point is sealed and the shaft can be rotated from outside the reactor using a motor.
  • the rotational speed of said rotary grate is adjustable such that the solids placed therein will be dissolved after a single turn of the grate.
  • the edge of said rotary grate is supported by a console mounted on the interior wall of the reactor.
  • the rotary grate remains rotatable and, thus, is easy to manipulate.
  • purifying jets are arranged around the rotary grate such that a cleaning fluid or fluid mixture can be sprayed onto the screen basket, thus preventing clogging of the meshes.
  • said purifying jets are arranged on a pipe which is led through the hollow shaft of the rotary grate into a space between screen basket and rotary grate and therefrom outside.
  • said pipe extends in the space from the outer end of a radial pipe section to an upward-bent pipe section.
  • the instant invention is illustrated in greater detail by the attached drawing showing a reactor for producing an aluminium alcoholate/alcohol mixture, the reactor comprising a screen basket with a rotary grate disposed thereabove.
  • the drawing shows a reactor 1 in a reactor housing 3 .
  • a screen basket 4 dividing the reactor into an upper section 3 b and a lower section 3 c .
  • a connecting line 3 f is provided for equalizing the pressure between lower section 3 c and upper section 3 b of the reactor.
  • Said connecting line 3 f is important for preventing disturbances in the screen basket 4 which may be caused by formation of reaction gas and vapor at the reactor bottom.
  • the screen basket 4 has orifices 4 a and is mounted (not depicted) on the wall 3 d of the reactor housing 3 .
  • Said vat, too, has orifices 5 a .
  • the rotary grate 6 is connected to a hollow shaft 8 led via a bearing 9 with stuffing-box and slide-ring packing to the toothed wheel 10 of a gear 11 .
  • Said toothed wheel 10 of the gear 11 intermeshes with a toothed wheel 12 driven by a motor 13 .
  • a feeding device 14 (not described in greater detail) through which, by means of a hopper 15 , aluminium lumps, preferably ingot off-cuts (even those of more than 1 kilogram in weight), can be filled into the reactor. Said lumps fall through the feeder 14 into a vertical pipe 17 , while passing several slides 16 which are opened and closed by turns. Said pipe 17 is disposed on a bearing 18 allowing to shift the lower outlet 17 a of the pipe 17 from the center of the rotary grate 6 to its edges, as indicated by the bidirectional arrow 19 .
  • the vertical pipe 17 is shifted by means of an adjusting device 20 disposed outside the reactor and connected with the vertical pipe 17 by means of a rod 21 .
  • the pipe 23 which is rotated with the shaft 8 is led to the edge of the interspace and upward.
  • the pipe sections leading to the edge 23 a of the interspace and then upward 23 b are provided with purifying jets 25 directed at the screen basket 4 .
  • Fresh hexanol can be charged to the reactor 1 via line 26 .
  • the fresh hexanol flows through line 27 to the interior 3 a of the reactor.
  • the aluminium particles employed are very coarse, preferably ingot off-cuts.
  • the space between rotary grate 6 and screen basket 4 is 5 to 10 cm.
  • the speed of drive 11 and 13 is adjusted such that the solids charged through the vertical pipe 17 and evenly distributed on the rotary grate 6 will be dissolved after a single turn of the grate. It is important that the aluminium lumps charged through pipe 17 onto the rotary grate 6 form a layer which is for example 10 to 15 cm thick.
  • an aluminium alcoholate/alcohol mixture will collect in the lower part 3 e of the reactor housing 3 .
  • Said mixture can be charged through lines 28 and 30 , via pump 29 , to the vat 5 .
  • the aluminium alcoholate/alcohol mixture is charged at high pressure such that the mixture is set bubbling, thus forming a spouted bed.
  • the bubbling liquid flows through screen basket 4 and rotary grate 6 over the aluminium lumps in the reactor.
  • the aluminum alcoholate/alcohol mixture flows through lines 31 and 27 to the upper part 3 b of the reactor housing 3 .
  • the mixture will immediately stop bubbling as the pump 29 is switched off.
  • the liquid will drop to the lower part 3 e of the reactor such that the aluminium lumps are no longer contacted by liquid. Thus, the reaction is suddenly interrupted.
  • Part of the aluminium alcoholate/alcohol mixture can be discharged via line 32 .
